MEANS FOR CLOSING AND SEALING MAILABLE PAPERS. A

Specification of Letters Patent.

Patented June 2, 1908.

Application filed July 3,1907. Serial No. 382,049.

To all whom it may concern:

Be it known that I, ROBERT M. KERR, a citizen of United States of America, residing at v2.820 I/Vest Chestnut street, Louisville, Kentucky, have invented new and useful Improvements in Means for Closing and Sealing Mailable Papers, of which the following is a specification.

My improvement relates to a means for closing and sealing letters, notes, circulars,

and other mailable papers, and is intended` to take the place of the ordinary envelop, thus making it possible to fold and mail a letter or other paper without an envelop, Furthermore it will be possible with my device to inclose checks, other papers, etc., and as in the ordinary envelop. y

When my letter paper is opened and the yflap torn away, the canceled stamp, post mark, and address will be found on one side of paper, and can be used as legal evidence that such paper has been mailed from one place to another.

The device by which, and the manner in which I attain these results is presently to be described.

Reference is now to be had to the drawing filed herewith, which drawing is to be considered a part of this specification.

In the drawing, Figure l represents an ordinary sheet of paper, such as is used as a business letter head, with an extendedportion gummed and perforated. Fig. 2, is a view of letter head after first folding. F ig.v

3, represents the sheet after the second folding. Fig. 4, shows third and fourth or transverse foldings. Fig. 5, letter fully folded and main flap D, bent or folded against letter. Fig. 6, shows letter fully folded, main flap affixed, and secondary or semi-circular flap G bent over, and affixed to reverse side of letter. Fig. 7, shows letter as folded, closed, sealed, stamped and addressed. Fig. 8

' shows letter sheet with an equivalent form of flap.

Like letters and figures of reference indicate different parts and features in the drawings.

In the drawing,`reference is now to be had to Fig. l, in which A represents the upper margin, C the line upon which the rst fold is creased, B a notch, a printed line, or perforations indicating the point where margin A must touch on first folding. D the main flap, E1, E?, E3, lines of perforations, F, F, portions of main flap intended to be gummed, and G secondary or supplementary flap, fully gummed.

Fig. 2, represents the sheet as firstA folded: A the upper margin, folded over, C first creasing, I, I, lower margin, D main flap, and II the line on which the next creasing is to be made.

Fig. 3 shows the sheet as twice folded, II being the last creasing, J, J, the side margins of the folds, K, K, lines upon which transverse creasings are to be hiade, and D, main flap. Fig. 4, K, K, outer margins of transverse folds, J, J, inner margins of the same. Fig. 5, K, K, outer side margins, J, J, inner margins, now under main flap D, E2, perpendicular line of perforation, E3 line of perforations separating main flap D and secondary fiap G.

Fig. 6, shows reverse side of letter to Fig. 5, G being secondary fiap bent over and affixed. Fig. 7, letter as folded addressed and ready for mailing.

Fig. 8 shows letter with an equivalent form of flap in which L is the body or letterportion, M the main flap, N, N, N, the several lines of perforations, O, O, the gummed portions of main fiap, P representing the fully gummed supplementary flap.

The manner of folding the paper will now be obvious. In Fig. l, the upper margin A is brought over to touch the notch B, creasing the paper along the broken line C, which now becomes the creased or upper margin C in Fig. 2. The upper margin, C, Fig. 2, is now bent over, and touches the lower margins I, I, creasing along the broken line II..

In Fig. 3, the lengthwise foldings are now complete, and the letteris now folded transe versely, the outer side margins J, J, creasing along the broken lines K, K, and the letter assumes the shape shown in Fig. 4, the creasings K, K, in Fig. 3, becoming the outer side margins, K, K, in Fig. 4 leaving the fol'dings now fiat neat and regular, with the flaps still extending downward. N ow the mam flap D, Fig. 4, is bent upward and creased along the line of perforations El, Fig. 1, and the gummed portions of said fiap as shown in F, F, Fi l, are moistened and struck along the fo ds K, J, K, J, Fig. 4, fastening them down securely, as shown in position of flap D, Fig. 5. The secondary semi-circular flap G, Fig. 5, still extends upward and is now ready to be bentl over and gunirned to the other side, as shown on the reverse or address side of letter, Fig, 6.

In Fig. l the main flap D, extends from the letter sheet along the line of perforations El: and another line of periorations E2, biseets said iap at a right angle to the iirst line of perforations. A Jfully gumnied secondary and semi-circular flap G extends downward from the lirst or main flap D, and is separated from said main i'lap by the line of perforations El. The lines of perforations described above are used to prevent mutilation of theletter sheet and 'facilitate its o ening. YWhen the letter is to be opened all t iat is necessary to do, is to tear away the flap along,- the `line of perforations El, beginning at the nppei` margin or' the folded letter or 'at .the line E3, separating` the flaps and tearing along'the upright line of perforations E2, when the letter is opened and the iiap detached.

I I/Vhile the Jform embodied in the foregoing description is the preferable forni of my invention, I do not desire to be eon'lined to the single form or' folding, or size, or forni of paper, or i'lap, but to any other form or forms of both, within the spirit of my invention.

Having thus described my invention so that one skilled in the art appertaining thereto may make and use it, I claim:

The combination of a mailable paper with an extended portion of the same, said extended portion eomprising a two part flap adapted to close and seal said inailable paper Jfor mailing when said paper is folded; said two part lap having thereon lines oi periorations, said two part iiap consisting of a partly gumined main flap integral at its base along` a iirst line of peiorations with said mailable paper, said main flap having` a iurther extended portion comprising a fully gummed supplementary flap integral with said main Hap along a seeond line oi perforations parallel to the first line, said main flap being biseeted perpendieularly through its center by a third line of periorations at a right angle to the iirst and second lines, all of said lines adapting said flaps to be easily torn away when said mailable paper so lolded, closed, and-sealed, is to be opened, substantially as described.

In testimony whereof, I have hereunto set my hand in the presenee of two subscribingI witnesses.
